MOP-WRINGER.

SPECIFICATION forming part of Letters Patent No. 436,428, dated September 16, 1890.

Application filed February 10, 1890. Serial No. 339 ,922. (No model.)

To all whom it may concern:

Be it known that I, GEORGE D. MUSSEY, a citizen of the United States, residing at De= troit, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements in Mop-Wringers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in mop-wringers, in which two corrugated rollers mounted in swinging uprights actuated by a treadle or foot-lever are brought together upon the mop, whereby by drawing the mop from between said rollers when the pressure is on the treadle the water is effectually wrung or pressed therefrom, all of which will be hereinafter more fully set forth, and the essential features of the device pointed out particularly in the claims.

In the accompanying drawings, forming a part of the specification, Figure 1 is a perspective view of the device, showing a vessel in position on the base thereof. Fig. 2 is a side elevation of Fig. 1, showing the rollers drawn together. Fig. 3 is a plan view of Fig. 2. Fig. 4 is an enlarged view of the spring that throws the rollers apart when the treadle is released. Fig. 5 is an enlarged detail of the treadle-bail, showing the loop formed therein in which the serrated tread-block is secured.

Referring to the letters and figures of refer-- ence, A indicates a base of any suitable material, preferably of metal. To the upper face of said base, near each corner thereof, is pivotally attached the lower end of the uprights D D, as shown at c, the upper ends of said up rights carrying the rollers B B.

The ends of the treadle-bail C are provided with a T-shaped head cl, that is centrally pivoted at a, to the upper end of the bracket E, secured to the base between the uprights D D, as clearly shown in Figs. 1 and 2. The outer ends of the cross-arms b b are pivoted at a to the uprights D D, respectively, and

the inner ends of said arms are pivoted at a to the T-head d of the treadle-bail, the arm I), attached to the upright D, being coupled to the lower end of the head cl, and the arm I), attached to the upright D, being coupled to the upper end of said head, (see Fig. 1,) whereby when the treadle is forced down the head cl is oscillated, drawing upon the arms I) and swinging the upper ends of the uprights in, carrying the rollers B together and into engagement withone another, as clearlyshown in Figs. 2 and 3.

The treadle-bail 0 extends around the up rights D, and at its center is formed into the loop f, in which is secured the serrated treadblock it, as clearly shown in Fig. 5.

The spring-bail F (see Fig. 4) is employed to throw the rollers B apart when the treadle is released. Said spring is formed of a continuous piece of metal, having the coils e e at the lower end of the vertical portions 25 t and the lips e e at the upper ends of said vertical portions and the arms 1; n connected by the horizontal portion 25'.

The spring F is secured to the base A at its lower ends 2 2. The vertical portions t extend upward near the inner face of the uprights D, and the lips e engage over the outer face of said uprights near their upper ends, as shown in Figs. 1 and 2. The armsoextend inward from the ends of the rollers at right angles thereto and form guards that prevent the mop from running off of the ends of the rollers when withdrawing the mop therefrom.

It will now be apparent that when the rollers B are brought together by means of the treadle, as before described, the coiled springs e will be compressed, and when the treadle is released the force of said springs acting on the uprights D will throw said rollers apart, the treadle-bail O arresting the uprights D when they have attained a vertical position, as shown in Fig. 1.

Itis designed that the uprights carrying the rollers 13 shall be of such height as to permit of the pail G being placed on the base A under said rollers, as shown. To wringa mop with this improved device, the wet mop is placed between the rollers B and said rollers brought together thereon by a downward pressure on the foot lever or treadle G. With the pressure still on the treadle the mop is drawn upward from between the rollers, whereby the water is effectually pressed or wrung therefrom.

The corrugated rollers B are arranged to mesh one with the other, as shown in Fig. 3, thereby more completely forcing the water from the inner portions of the mop than could be. accomplished were smooth rollers employed and also preventing the mop from running to one end or the other of the rollers when the mop is being withdrawn therefrom, as in the act of squeezing or wringing the mop. When the mop has been withdrawn from the rollers, the pressure on the treadle is released, when the spring-bail F will throw the rollers B apart, as shown in Fig. 1.

Having: thus; ,fully set forth my invention, whatI claim as new, and desire-to secure by Letters Patent, is. I

1. In combination with the base, the swinging uprights pivoted to the base at their lower o ends and. carrying the rollers in theirupper- 7 ends, the ,treadle-bail having the T-shaped;

heads, the brackets pivotally supporting the heads of said bail, the cross-arms pivoted to the heads of the bail and t0 the swinging uprights, as set forth, the spring-bail F, attached to the base and having engagement with the uprights D, as and for the purposes specified.

2. In combination with the base, the uprights D D, pivotally coupled thereto, the corrugated rollers journaled in the upper ends of said uprights, the brackets E, the treadlebail pivoted to said brackets, said bail having the T-shaped heads and the loop f, the tread-block in said loop,'the arms I) b, pivoted to'the T-shaped heads and to the uprights D D, as specified, and the spring-bail F, the whole operating in the manner andfor the purposes specified.

In testimony whereof Iaffix my signature in Y 1 presenceof two witnesses.-.
